J&R wants to make sure you can buy electronics on Park Row — whether it’s running a shop there or not.

The giant electronics store abruptly closed its doors Thursday after more than 40 years of selling TVs, VCRs, cameras and vinyl records at a hodgepodge of storefronts across the street from City Hall.

Now, J&R owners Joe and Rachelle Friedman — who own buildings at four Park Row addresses between Beekman and Ann streets — are in talks to create an electronics-focused shopping mall that could play host to a number of gadget and tech brands, sources told The Post.

The twist: J&R will no longer operate the stores, but instead will act as the developer and landlord for the new venue — slated to open in 2015.

“It’s pretty safe to say J&R’s days as a brick-and-mortar retailer are behind it,” an insider briefed on the plans said.

J&R — which had weathered the 2001 attacks on the World Trade Center, just a few blocks away — will continue to sell electronics online, at its own namesake site and through Amazon, sources said.

The Friedmans, through a spokesman, declined to comment about possible other uses for the buildings.

“Everything is on the table right now,” the source said, noting that the Friedmans retain valuable air rights for potential high-rise developments.

In February, J&R settled about $15 million in vendor claims after a disappointing holiday season, sources said. Shortly after Christmas, J&R closed the fourth floor of its main store — among the last retail spaces in the city devoted to classical music CDs.
